Description
BACKGROUND OF THE INVENTION
This invention relates to a convertible structure which can be
assembled for use either as a pet home or as an exercise pen for
the pet and which can be readily converted between the two uses.
The invention is intended primarily for use as a dog home and
exercise pen but can also be used for other animals such as
rabbits.
Separate dog homes and exercise pens are currently available and if
pet owners desire each item, they must make two separate purchases.
This is a large outlay, since each item can be somewhat expensive.
The current practice is also inconvenient in its use of storage
space, since typically only one item is in use at any time, and is
wasteful of materials in that similar wall panels may be used in
each product, but are not utilized together.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a combination structure
which can be assembled either as a pet home or as an exercise pen,
which can be readily converted between the two uses and which can
be knocked down, when not in use to form a compact readily
transportable and storable package.
It is another object of the invention to provide a combination
structure as above which is converted from a home to an exercise
pen by the addition of a wall module assembly. A further object of
the invention is to provide the combination with the facility for
adding further wall module assemblies, as required, to increase the
size of the exercise pen.
Another object of the invention is to provide a combination
structure, as above, which is more economical to manufacture and
purchase than a separate pet home and exercise pen of comparable
scale.
Still another object of the invention is to provide a combination
pet home and exercise pen in which maximum use is made of the wall
panels of the pet home when converting the structure into an
exercise pen.
Yet another object of the invention is to provide a combination pet
home and exercise pen which is simple to set up, take down and
convert from one use to the other.
Generally stated, the invention provides a combination pet
home/exercise pen structure comprising a plurality of
interconnected hinged panels, preferably wire mesh panels, which
fold into a compact package with the panels overlaid one on
another, which can be erected into a pet home having a base, side
walls, end walls and a flat roof, by unfolding the panels and
clipping adjacent panel edges together, and which can be converted
from a pet home to an exercise pen by unclipping the panels,
setting the pet home on one end, folding the end walls in against
the base, opening out the side walls and roof and clipping one or
more additional wall module assemblies (each comprising two or more
hinged wall panels of similar configuration to the side wall
panels) to free outer edges of the one side wall and the roof
respectively to form a pen enclosure.
In a preferred form of the invention, the base of the structure may
comprise upper and lower walls defining a compartment therebetween
forming a storage receptacle for the additional pen-forming wall
module assembly with its respective panels folded together one
against another. The base may also include a second compartment for
a slide-out tray for pet droppings, etc.
Conveniently, hooks may be provided at the edges of selected walls
of the structure for hooking onto end rods of adjacent walls to
clip the walls together when the structure is erected and which can
readily be unhooked when the structure is to be folded. The
configuration of the clips, the side walls, the end walls and the
roof, may be such that in the erected position of the pet home, the
roof can be unhooked from the side walls and end walls and hinged
open, like the lid of a box, without affecting the integrity of the
side walls and end walls. Other forms of clipping means can also be
used however.
A first pet access door may be provided in one of the end walls and
a second pet access door may be provided in one of the panels of
the additional wall module assembly. The pet home portion of the
structure can be sold separately (without the additional wall
module assembly) for users who do not require the exercise pen
facility and likewise, additional wall module assemblies can also
be sold separately as add-ons. The size of the exercise pen can be
increased by further add-on assemblies, as required.
Additional features and advantages of the invention will become
apparent from the ensuing description and claims read in
conjunction with the attached drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS
The drawings show a collapsible structure 10 (FIG. 1) which can be
erected to form a dog home as illustrated in FIGS. 3-3E, which can
be converted from the dog home into an exercise pen for the dog as
shown in FIGS. 6-7, and which can be folded and collapsed into a
flat compact package as shown in FIG. 1. The collapsible structure
comprises two basic modules, namely a dog home forming module 12
and an additional pen-forming wall module 14, both of which modules
are made up of wire mesh panels or grids.
The home forming module 12, (See particularly FIGS. 1-3) comprises
a rectangular base 15 with a top wall 16, end walls 18, 20 hinged
to opposite ends of the base, side walls 22, 24 hinged to opposite
sides of the base and a roof 26 hinged at one side to the top edge
of side wall 24. The end walls 18, 20 can fold down onto the top
wall 16 of the base one over another, followed by side walls 22 and
24 and roof 26, which can fold down onto side wall 24. Thus module
12 can be collapsed into the compact substantially flat package
shown in FIG. 1.
The base 15 is formed by upper and lower shallow rectangular trays
28, 30 both made of wire mesh and which may be secured together by
crimped cylinders 31 (see FIGS. 3A and 3D) engaged around adjacent
rods of the respective trays, or by other suitable attachment
means. Top wall 16 is similarly attached to tray 28. Tray 28 forms
a receptacle for a slide-in animal droppings pan 32 and tray 30
forms a receptacle for folded wall forming module 14. A bar 36 at
one end of tray 30 (see FIG. 3A) forms a stop for module 14 and
bars 38 at the opposite end of tray 28 form a stop for pan 32. A
pivotal wire rod clip 40 may be provided at the other end of tray
28 to form a releasable catch holding pan 32 in place. Clip 40 is
similar to clip 26 which is disclosed in copending application Ser.
No. 08/459,497 field Jun. 2, 1995 and commonly assigned herewith,
the contents of which are expressly incorporated herein by
reference.
End walls 18 and 20 are pivotally connected to opposite ends of top
wall 16 by further crimped cylinders 31. At its sides, tray 28
extends somewhat above wall 16, and wall 24 is pivotally attached
at one side of tray 28 by additional crimped cylinders 31 while
wall 22 is similarly attached to the other side of tray 28 at a
slightly higher level so that the side walls, end walls and roof
can be folded down onto the base in a stacked arrangement as shown
in FIG. 1. Roof 26 is pivotally connected to side wall 24 by
further crimped cylinders 31. (In the pivotal connections between
the respective walls, it is understood that in each case, the
cylinders 31 are crimped around adjacent end rods of the grids
forming the respective walls as, for example, the end rods 24a, 26a
shown in FIG. 3E by way of example.)
The roof 26 is provided along its free edges with hooks 42 for
releasably clipping the roof to side wall 22 and to end walls 18,
20. The side walls 22 and 24 have like hooks 42 at their opposite
ends for releasably clipping to the end walls 18, 20. As shown in
FIGS. 8 and 9, each hook 42 is formed from a wire rod bent in a
yoke-like shape with elongated legs 42a welded to a respective one
of the walls 18-24 or roof 26, and a resilient saddle-shaped top
hook portion 42b which is depressed at 42c to provide a resilient
obstruction for an end rod of one of the walls of the structure
when it is fitted into the hook. In each case, the hooks are welded
in place so that the closed end of the hooks project slightly from
the end of the respective wall on which they are attached. The
arrangement is such, in each case, that as the structure is
unfolded and opened out, the end rods of the respective walls can
be push fitted into the hook of an adjacent wall to connect the
walls together into a rigid elevated structure. FIG. 3E shows, for
example, how end rod 18a of wall 18 fits into hook 42 on the roof
26 and how end rod 18b fits into hook 42 on the side wall 24. As
seen in FIG. 3, the roof 26 has three hooks 42 along one side to
connect with side wall 16 and two hooks 42 at each end to connect
with end walls 18 and 20. The side walls 18 and 20 have two hooks
42 at each end to connect with the end walls 18 and 20. The
remaining figures show a smaller model in which the number of roof
hooks is reduced by one along each side of the structure.
End wall 18 has a pivotal lift-up animal access door and latch
structure 44 for the dog home of like form to the door structure 28
described in the above-noted copending patent application and the
details of which will not therefore be described herein. Reference
is made to the copending application for such detail. When erected,
the dog home is used in known manner and it will be understood that
it can again be collapsed and folded, when required, by reversing
the steps described above.
When the structure is collapsed into the package shown in FIG. 1,
end walls 18, 20 are folded down onto base wall 16 with wall 18
lying over wall 20. Side wall 22 at its upper end is hooked to roof
26 by the hooks 42 along the side edge of the roof but all of the
other hooks 42 are disconnected. This allows the side walls and
roof to be folded down as a hinged unit onto base wall 16 over the
end walls 18, 20 with side wall 24 lying over end wall 18, roof 26
lying over side wall 24 and side wall 22 at the top.
To elevate and erect the structure into a dog home, wall 22 and
roof 26 are lifted by their hocked-together edges, see FIG. 2 and
the side walls and roof are unfolded, opened out and elevated into
an open-ended box as seen in FIG. 2A. Then, the end walls 18, 20
are raised from the base and their edges are engaged in the hooks
42 provided at the ends of the side walls and roof. This forms the
structure into a rigid dog home as shown in FIG. 3. To collapse the
dog home, the procedure is reversed, the end walls first being
unhooked and folded down onto the base and the hooked-together side
walls and roof being mutually folded and collapsed back through the
FIG. 2 configuration down onto the base over the end walls. In
these operations, the roof remains hooked to side wall 22 and the
hooks 42 act as hinges during the unfolding and folding
operations.
According to another feature of the invention, when the dog home is
erected as shown in FIG. 3, there is sufficient flexibility in the
structure to allow all of the roof hooks 42 to be released, by
pressing in the top edges of the side walls and end walls while the
wall hooks 42 remain engaged, so that the roof 26 can be hinged
open in the manner of a box lid as shown in the dotted line
position. The roof can be hooked again to the side walls and end
walls in similar manner.
The dog home shown in FIG. 3 can be formed into an exercise pen in
the manner illustrated in FIGS. 4 to 6 by using the additional
wall-forming module 14. As shown in FIG. 4, the home-forming module
12 is set on one end, and the end walls 18 and 20 are folded in
against the base 15 (or are kept folded against the base if
starting from FIG. 1). A pivotal S-type hook 46 (FIGS. 3A, 3B) may
be provided on a rod of one end wall to clip an adjacent rod of the
other end wall to retain the end walls in place against the base.
For this operation, the roof 26 is unhooked from side wall 22, side
wall 22 is folded out to the position shown in FIG. 4, as are the
side wall 24 and roof 26.
The additional wall-forming module 14, in the illustrated
embodiment, is formed by four pivotally interconnected walls 48,
50, 52, 54 each formed by a metal grid of the same dimensions as
the side walls 22, 24 and being pivotally interconnected along
their longer edges by additional crimped cylinders 31. Walls 48-54
can fold against one another as shown in FIG. 1 to fit into tray 30
and can be removed and opened out to the position shown in FIGS. 5
and 6 to be attached to the home-forming module.
Wall 54 has hooks 42 along one edge to fit with end rod 22a of wall
22 (FIG. 7c) and the end rod of wall 48 fits into the hooks 42 on
the adjacent edge of wall 26 to form the structure into an enclosed
exercise pen as shown in FIG. 6. Wall 52 has a cut-out 52a (See
FIG. 5) for a pivotal access door 52b secured by crimped cylinders
31 and provided with releasable S-type clips 46 for opening and
closing the door. It is evident that the exercise pen can be
readily dismantled and folded away into the package shown in FIG.
1. Additional S-type hooks may be provided on the roof 26 or wall
24 to clip onto wall 22 in the folded condition of the structure to
retain the walls in place.
It is evident that the exercise pen can be readily reconverted into
the dog home, or knocked down and refolded into the package shown
in FIG. 1.
If a larger exercise pen is required a second wall module like wall
module 14 and comprising walls 48', 50', 52', and 54' can be
connected between wall 54 and wall 22 as shown in FIG. 7.
While only preferred embodiments of the invention have been
described herein in detail, the invention is not limited thereby
and modifications can be made within the scope of the attached
claims.
